The question explore wether the concept of world-system theory still works in the modern society
Thank you, Mr. Kolley, for a good question!
In my opinion, Wallerstein's idea is useful while analyzing current social & political processes on our planet. In my university practice, through the prism of this concept, I manage to explain a lot more clearly to students.
By the way, the frequency of the word "world-system" on the Russian Science Citation Index: in 5 years there were 3 papers with the word "world-system" in the title and during last year - 75 articles with the word "world-system" in "keywords" (https://elibrary.ru/query_results.asp).
Conclusion: in Russia, for example, Wallerstein's concept is actively used in scientific usage
Korenkov Alexander Thank you for the contribution and the references in supporting your argument.
First and foremost, in my view the world system theory still function is modern society. In other words, the concept still remains significant in present-day society as it provides crucial insights into global disparities and the interconnections between states within the free-market world economy.
